Tso lus
Yog koj tab tom nrhiavASTM B677 904L stainless hlau kavrau cov khoom siv hluav taws xob uas muaj kev tiv thaiv corrosion siab, siab ua haujlwm siab, thiab tsim nyog rau siab -kev siv kub, peb tuaj yeem muab koj nrog ntau yam kev lag luam txhim khu kev qha- qib yeeb nkab daws teeb meem, tshwj xeeb tsim rau tshuaj lom neeg, petrochemical, thiab high - khoom siv hluav taws xob kawg.
PebASTM B677 904L stainless hlau kavyog tsim los siv cov txheej txheem seamless los yog tsis kam welding, ua rau cov phab ntsa tuab tuab, siab qhov tseeb, thiab du sab hauv thiab sab nrauv kom yooj yim installation thiab tom qab ua tiav.904L stainless hlau kavmuaj PREN tus nqi ntau dua los yog sib npaug rau 40, nrog tus nqi corrosion tsuas yog 0.12-0.15 hli / xyoo hauv 20% sulfuric acid ntawm 80 degree, uas yog 3.3-5.4 npaug ntau dua corrosion resistant dua 316L. Hauv cov xov xwm tsis muaj zog acidic nrog cov ntsiab lus chloride ion siab (20000 ppm), tus nqi corrosion tsawg dua los yog sib npaug li 0.3 hli / xyoo, tiv thaiv kev cuam tshuam ntawm intergranular corrosion thiab kev ntxhov siab corrosion. Lawv tau dav siv nyob rau hauv tshuaj thiab petrochemical tshav kub exchangers, kws tshuaj, seawater desalination systems, high-temperature thiab high-pressure pipelines, thiab corrosive media tsheb thauj mus los systems.
GNEE muaj ntau yam ntawmASTM B677 UNS N08904 seamless kub exchanger raj, nrog cov kab npoo sab nrauv npog 9.52-119mm thiab phab ntsa thicknesses ntawm 0.8-12.7mm. Kev cai ntev ntawm 3-6m muaj. Cov kav dej no zoo kawg nkaus haum rau lub plhaub-thiab-tub thiab phaj kub exchangers. Txhua yam khoom tiav dhau los kuaj hydrostatic thiab ntsuas tam sim no. Sab nraud txoj kab uas hla yog tswj nyob rau hauv ± 0.38mm, thiab sab hauv phab ntsa yog du thiab tsis muaj impurities, uas ua rau ib tug 15% nce nyob rau hauv tshav kub exchanger efficiency. Txhua batch los nrog MTC cov ntaub ntawv pov thawj, kom ntseeg tau tias lub sijhawm ntev ruaj khov ntawm cov khoom siv hluav taws xob sib pauv.
